Default Re: How tight should a rebuilt engine be?

I suppose there could be many differences depending on the engine. I had an engine rebuilt and had it in my garage for eight years before I was ready to use it. It was incredibly tight. I used 12 V on the starter and towed the car with my tractor (very slowly in third gear), let out the clutch very slowly until I could hear the clutch start to grab and then hit the starter. When the fan started turning, I let the clutch all the way out and towed it about a mile. I did have the plugs out. It was enough to loosen things a bit. I reinstalled the plugs and towed the car again and I had it running in about 100 ft of towing.
Good luck with it. Ed
